Evans Water-free Coolant

[vr2turbo]

Izso, the engine was down for a rebuild so just add when it was assembled.

pomen, brake fluid is corrosive wei....

Corrosive on paint and copper...

 

[Izso]

i wouldnt try brake fluid....


but if i got a whole lot of glycol (ethylene glycol) then maybe i'll try using it in pure form...

You can't. ethylene glycol by itself is corrosive I think. And the heat transfer properties is poor if I remember my chemistry 101.

well...since u were saying brake fluid...

here is what i found:

https://en.wikipedia.org/wiki/Brake_fluid
DOT Brake Fluid vs. Mineral Oil - and the Winner is.. | Epic Bleed Solutions


DOT3 brake fluid boiling temp was exactly at 190degree C...which makes the evan waterless coolant sounds pretty much like a brake fluid...


plus brake fluid also content GLYCOL which is also happens to be content of a coolant

Aiyo.. it's not brake fluid + ethylene glycol la. It's probably some petroleum based chemical mix with ethylene glycol la.

Waterless coolant sound very appealing due to the fact that it can minimise rust issues to almost zero. But I am having reservations as to what chemicals are they using that has to ability to match the specific heat capacity and specific latent heat of water. Up till now, nothing beats water in terms of cooling. But I'm waiting for the famed myth-buster sifu for his review

i think from previous comment saying that faster engine warm-up shows that it has less than water thermal capacity.....but probably since a good working fan/radiator able to cope with that, should be no problem for that

i was halfway correct:

Gosh is it corrosive?? Never knew that. Anyways, I've seen some brands that are slightly more expensive using propylene glycol now.

This Evans Waterless Coolant sounds like a really good product. But i have to agree, it is really expensive for a coolant. RM600 to do the whole thing. And if anything happens which requires a top-up, is another RM300 a bottle. That damn painful. But where to get it in Malaysia?

What about that Engine Ice? Where to get it and how much does it cost?

 

[vr2turbo]

Can Try Lubegard Kool It also.....

 

[DanzEterna]

if change water pump need to pay rm300 for top up?

 

[vr2turbo]

RM300 for a fill, so if change water pump make sure collect everything. Spill some and not enough got to buy to top up....lol

I managed to get my hands on a laser thermometer and it's pretty accurate. I have ideas on how to test this but i don't have the budget to buy a RM300 bottle of Evans for testing. And no I'm not referring to myself as the famed mythbuster, just have ideas.

Lubeguard kool and Engine Ice is like Permacools premix. These are already premixed coolants from what I can make out in the website. Meaning they are glycol based products mixed with water. Engine Ice is Propylene glycol mixed, Permacool is ethylene glycol mixed, Evans has is both propylene glycol and ethylene glycol but oil based somehow. Not sure.

Glycols generally are good conductors of heat but are flammable. So not sure how that works for us as a coolant.

Evans has a distributor in KL, forgot the name. Need to dig out the name card I took the other day.

Not exactly, they sell in 4L bottles, since each bottle is RM300 then yes. But it's not per top-up. However if installed correctly, there shouldn't be any need to topup if there's no catastrophic failure in the engine head gasket or hoses.

in its pure form it is I think. premixed it isn't but it still will break down due to the water combination, hence the need to change radiator water every now and then.

Yup, Kool It is additive to water or water with other coolant.

Danz did mention water pump failure....lol

Wonder why new car coolant can last or maybe old car engine block already rusty. VR with Toyota LLC will break down and need flush in 2 years. Chery original now 5 years still nice and clean...

 

[Izso]

New car coolant can last because no corrosion or breakdown of coolant inside the system. If diligent and change every x amount of KM / years, then it'll never have issues I personally think.

After thinking about this a while, I've decided the following :

1. Radiators and hoses are inexpensive. My old car radiator brand new was less than 300 to buy. New hoses 30-40 each.
2. Coolant is cheap to buy. So is distilled water.

So no matter how I calculate I cannot justify the cost for a waterless system (600). So my conclusion is unless someone is sponsoring me to do the test for them, I'll never spend a cent on this system.

As per your first paragraph, looks likely it is more worth the change to Evans when car is new. If engine block already rusting, might just contaminant the Evans, and may not last....

I remember the product. But forgot the name. I just remember seeing a video about the product. And its the same Evans brand that you guys are saying. This video also answers a lot of questions posed by everyone here.

Surprisingly, it also cost around RM900 to flush and fill in USA.
